ASRC IP
ASRC IP cores (Asynchronous Sample Rate Conversion) convert stereo audio from one sample frequency to another. The input and output sample frequencies can be an arbitrary fraction of one another or the same frequency, but based on different clocks. The output is a band-limited version of the input resampled to match the output sample timing.
